Yeah people don’t seem to be understanding that this is a technical and pragmatic issue, not a business decision.
It’s the “new and improved” problem. If it’s new, it’s not improved. And if it’s improved, it’s not new.
If you want a new, cutting edge game, you aren’t just improving the old game. So the old stuff likely won’t be compatible.
If you want an improvement/extension of the old game, you won’t be getting a shiny new game.
They made the choice to make a shiny new game but they need to try to prevent the inevitable backlash from people being upset that they’re favorite X/Y/Z is missing.
